IXTH12N100L Equivalent & Substitute Parts

Part Overview

The IXTH12N100L is an N-Channel MOSFET manufactured by IXYS, rated for 1000V drain-to-source voltage with 12A continuous drain current at 25°C. This device is housed in a TO-247 package and is designed for high-voltage switching applications requiring through-hole mounting. The part is currently in active production status with 3400 units in stock.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining compatibility with the application's thermal, voltage, and current requirements. Alternative models may be necessary due to inventory availability, lead time considerations, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXTH12N100L is determined by the following critical parameters:

Voltage Rating: The substitute must support the application's maximum operating voltage. The IXTH12N100L operates at 1000V Vdss. Substitute parts with equal or higher voltage ratings are acceptable for direct replacement.

Current Rating: The substitute must support the continuous drain current requirement of 12A at 25°C. Parts with equal or higher current ratings maintain thermal margin and switching performance.

On-State Resistance (Rds On): This parameter directly affects power dissipation and thermal performance. Substitutes with comparable or lower Rds On values ensure equivalent or improved efficiency.

Package and Mounting: The TO-247-3 through-hole package is a standard form factor. Substitutes must use identical or mechanically compatible packaging to ensure PCB layout compatibility and thermal management effectiveness.

Temperature Range: The operating temperature range of -55°C to 150°C must be maintained or exceeded by substitute parts to ensure reliability across the full application temperature spectrum.

Compliance and Status: Both the main part and substitute must maintain active product status and equivalent RoHS3 compliance to ensure long-term availability and regulatory conformance.

Parameter Comparison

Engineering Selection Recommendations

IXTH12N100L (Primary Part)

The IXTH12N100L remains the primary selection for applications requiring the full specified performance envelope. This device delivers 1000V voltage rating, 12A continuous current, and 400W power dissipation capability. The part is in active production with substantial inventory availability (3400 units). RoHS3 compliance and REACH unaffected status confirm regulatory alignment for current and future deployments.

STW6N95K5 (Substitute Part)

The STW6N95K5 from STMicroelectronics is an active-status substitute suitable for applications where the voltage and current requirements are within reduced specifications. This device operates at 950V Vdss and 9A continuous drain current, with a maximum power dissipation of 90W. The part maintains identical operating temperature range (-55°C to 150°C) and TO-247-3 package compatibility. RoHS3 compliance and active product status ensure regulatory conformance and supply continuity.

Substitution Constraints

The STW6N95K5 is appropriate only for applications where:

• Maximum operating voltage does not exceed 950V
• Continuous drain current requirement does not exceed 9A
• Power dissipation budget does not exceed 90W

Applications requiring the full 1000V rating, 12A current capacity, or 400W power dissipation must use the IXTH12N100L. The reduced specifications of the STW6N95K5 make it unsuitable as a direct replacement in high-power or high-voltage margin applications.

Frequently Asked Questions (FAQ)

Q: Can the STW6N95K5 be used as a direct replacement for the IXTH12N100L in all applications?

A: No. The STW6N95K5 has reduced voltage (950V vs. 1000V), current (9A vs. 12A), and power dissipation (90W vs. 400W) ratings. Substitution is valid only when the application operates within these lower specifications.

Q: What is the primary difference in electrical performance between these two parts?

A: The IXTH12N100L provides higher voltage headroom (1000V), greater current capacity (12A), and significantly higher power dissipation capability (400W). The STW6N95K5 offers lower gate charge (13 nC vs. 155 nC) and reduced input capacitance (450 pF vs. 2500 pF), which may provide faster switching characteristics in lower-power applications.

Q: Are both parts mechanically compatible in the same PCB layout?

A: Yes. Both devices use the TO-247-3 through-hole package with identical pin configuration and mechanical dimensions. PCB layouts designed for the IXTH12N100L accommodate the STW6N95K5 without modification to mounting holes or thermal management structures.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the IXTH12N100L and STW6N95K5 are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain active product status with unlimited moisture sensitivity level (MSL 1).

Q: What is the impact of the lower gate charge in the STW6N95K5?

A: Lower gate charge (13 nC vs. 155 nC) reduces the energy required to switch the device and may enable faster switching transitions. This characteristic is beneficial in applications where switching speed and gate drive efficiency are critical, provided the voltage and current requirements remain within the STW6N95K5 specifications.

Q: Can the IXTH12N100L be used in place of the STW6N95K5?

A: Yes. The IXTH12N100L can be used in any application designed for the STW6N95K5, as it exceeds all electrical specifications. However, this substitution may result in unnecessary cost and thermal design margin beyond application requirements.

Q: What inventory considerations apply to these parts?

A: The IXTH12N100L has 3400 units in stock, while the STW6N95K5 has 65200 units available. For high-volume production or extended lead time scenarios, the STW6N95K5 may offer supply advantages if application specifications permit its use.
